I watched it again. I still think she was referring to marrying Brady. That would make her Sami's sister-in-law and technically "more than Sami's children's aunt". :shrug:

Oh, it would make her more related to Sami not more related to Sami's children. Yeah, that could have been worded better.

Well, Kristen is also "more" in the sense that she's Sami's mother's arch nemesis and Sami's stepfather's former lover/fiancee. And heck, if she turns out to be EJ's mother, then that would classify as "more," too. So many possibilities...
